When it comes to solar as a renewable power source, there have been two main challenges – efficiency and cost. To gain a boost in total system efficiency when using solar power, many engineers are switching to GaN FETs in their solar inverter designs.
Photovoltaic (PV) single-phase string inverter
When it comes to renewable energy, solar panels have been at the forefront of developments for some time. However there is still an efficiency question over their performance, with even the latest photovoltaic (PV) technologies delivering around 20% efficiency when it comes to converting sunlight into electricity. Residential and small commercial solar installations up to about 5 kW, tend to use a multiple strings of 360 W to 400 W panels. In both the DC boost stage and AC inversion stage, GaN FETs provide an significant boost to overall system efficiency and a reduction in inverter size, weight and cost.
